MAX1123 - 210Msps Analog-to-Digital Converter

Description

The MAX1123 is a monolithic 10-bit, 210Msps analogto-digital converter (ADC) optimized for outstanding dynamic performance at high IF frequencies up to 500MHz.

The product operates with conversion rates of up to 210Msps while consuming only 460mW.

Features

  • a selectable on-chip divide-by-2 clock circuit, which allows the user to apply clock frequencies as high as 420MHz. This helps to reduce the phase noise of the input clock source. A differential LVDS sampling clock is recommended for best performance. The converter’s digital outputs are LVDS compatible, and the data format can be selected to be either two’s complement or offset binary. The MAX1123 is available in a 68-pin QFN with exposed paddle (EP) and is specified over the industrial (-40°C t.

19-3028; Rev 1; 2/04 www.DataSheet4U.com 1.8V, 10-Bit, 210Msps Analog-to-Digital Converter with LVDS Outputs for Wideband Applications General Description The MAX1123 is a monolithic 10-bit, 210Msps analogto-digital converter (ADC) optimized for outstanding dynamic performance at high IF frequencies up to 500MHz. The product operates with conversion rates of up to 210Msps while consuming only 460mW. At 210Msps and an input frequency of 100MHz, the MAX1123 achieves a spurious-free dynamic range (SFDR) of 74.5dBc. Its excellent signal-to-noise ratio (SNR) of 57.4dB at 10MHz remains flat (within 1.5dB) for input tones up to 500MHz. This makes the MAX1123 ideal for wideband applications such as digital predistortion in cellular base-station transceiver systems.
